Solitons are waves with just a single crest. They result when a wave’s natural tendency to spread as it propagates is cancelled out by an inherently nonlinear phenomenon known as self-focusing. This means that solitons can travel a long distance whilst maintaining their same shape.

    Light propagating in the topological edge channel of an array of ring resonators is predicted to generate nested frequency combs: like a Matryoshka doll containing a set of smaller dolls, each ‘tooth’ of the comb comprises another frequency comb.

    Among the many reasons a signal may deviate from perfect periodicity, quantum-limited jitter is arguably the most fundamental. A clever experiment has now stripped away technical noise to unveil quantum-limited jitter of ultrafast soliton frequency combs.
